HANS F. MAHLSTEDT, or GILMAN, IOWA HOG TROUGH Application filed April 7,1928. Serial No. 268,202.

/ My invention relates to a trough to be used for feeding or wateringanimals, especially hogs, and has for its object to provide a trough ofthe type disclosed in the issued patent of Alfred J J ahde, #1,531,617,issued March 31, 1925. r

More specifically, it is my object to provide a trough of this typehaving means for securing it to a stationary support so as to preventtipping and to simplify and cheapen the construction of such a troughwithout sacrificing durability or strength.

Another object of my invention is to provide atrough, the W ll of whichmay be made in three pieces, a reinforcing member being provided,adapted to permanently secure the three pieces together and adapted alsoto provide means for supporting the trough rigidly upon a stationarysupport. Thus the supporting members become an integral part of thetrough and the construction of the trough is clearly simplified.

With these and other objects in view, my invention consists in theconstruction, arrangement and combination of the various parts of mydevice, whereby the objects contemplated are attained, as hereinaftermore fully set forth, pointed out in my claim, and illustrated in theaccompanying drawings, in

which Fig. 1 is a perspective view of the preferred form of my inventioninstalled in connection with a stationary support.

' Fig. 2'is a plan view of the trough.

Fig. 3 is a transverse, sectional view, taken on the line 33 of Fig. 1.

Fig. 4: is a similar sectional view, showing 3 a somewhat modified formof my invention.

The two end walls 10 of the trough are substantially triangular shaped,as clearly illustrated in the drawings, with their rear edges vertical,as at 11, and their forward ends inclined inwardly and outwardly, as

' at 12. The upper edges of the end walls 10 are. rolled outwardly andaround the side arms 13 of the longitudinal yoke, which is a U shapedmember formed of a piece of heavy steel wire, joined with the'threeportions 13 5G and 1% at right angles to each other.

A single, rectangular sheet of material is employed to form the frontand rear walls 15 and 16, respectively, which are connected by a curved'bottom. The rear wall 16 is vertical and the front wall 15 is inclinedat the proper angle to correspond to the forward edges 12 of the endwalls 10. The upper edge of the forward wall 15 is rolled outwardlyaround the member 14: of the reinforcing yoke and the upper edge of therear wall 16 is rolled around a cross member 17, which is formed of wireand secured at its end tothe arms 13 of the yoke. As shown in thedrawings, the preferable method of securing is by looping the ends ofthe cross member 16 about the side arms of the yoke.

The edges of the end walls 10 and the walls 15 and 16 are joinedtogether by any I method such as by folding, crimping, soldering orwelding. Almost any water-tight joint will be sufficient for the reasonthat the strains to which the trough will be subjected are borne by thewire reinforcing members almost entirely. Since a hog trough receivesvery rough usage, this is an essential feature of my invention.

One of the requirements for a hog trough is that'it shall be secured sothat it cannot be tipped over by the hog. The hog, in rooting with hissnout, is capable of exerting considerable pressure.

In order to'attain maximum strength, I form the elements by means ofwhich the trough is secured to. a stationary support, as integralcontinuations of the reinforcing yoke. The side arms 13 are extendedbeyond the cross brace 17, as at 18 and in the preferred form of myinvention are bent downwardly to form hooks 19, adapted to be receivedin vertical openings 20 in a sta tionary support 21, such as ahorizontal rail of a fence or a portion of a gate or a hog house or thelike. The hook 19 is made parallel to the rear wall 16 so that the wall16 may abut flatly against the member 21. In this way, should the hogput its feet into the trough and allow its weight to rest in the trough,the pressure will be borne partly by the hook 19, partly by the extendedarms 18 and partly by the rear wall 16.

Upward pressure of the snout of the hog against the trough will be borneentirely by the hook 19.

In the modified form of my invention, shown in Fig.4, the armsl8a'areiniade long enoughto extend clear thrloughthe sta'tion-, f arysupport 21a and at their endsare curled to form rings 22, through whichpins 23 are inserted to engage the rear face-ofi-'the*stationary members21a. Upward pressure in,

this'case is borne by the arms 18a, engaged" against the upper limitoil-the. slot 28 in the support 21a. The slot 23" ismade large enoughto: allow entrance ofthe'rin-gs 22.

. No matter where-:the-hogmay applypressure to the trough, this pressureWill 7 be transmitted directly to the reinforcing yokeforminganintegral-part of the trough and hence to the integral arms ofthe. yoke: There' will be lie-possibilityof:looser-ringv the joints atthe cornersof; thetrough or looseniang the conneotionof-f thesupporting-arms with the: trough; At the;sametime the constructionissimplified and eheapened: The wallsmaybe first-secured to the-yoke andthensol-dered together;,'the yoke acting to retain them i-n' theirproper: relationshipi The necessity;- of f'nimlyfsecuring thesupporting; arms" to the trough is, eliminated;
